Application filed October 1, 1314. Serial No 86%,377,

To all whom it may concern Be it knownthat I, FREDERICK C. WARNE,

class or type known as riding cultivators.j

The primary object of this invention is to provide means whereby theshovel or cultivator gangs may be raised or lowered independently ofeach other through the medium of independent gang actuating levers, ormay be raised and lowered simultaneously through the medium of a masterlever connected to a rock shaft connected to and adapted tosimultaneously actuate said independent or gang actuating levers.

A further object is to provide means for assisting in the simultaneousraising or elevation of the gangs through the medium of the master leverand rock shaft by utilizing the weight of the rider or operator in theseat through the medium of a seat beam which is transformed into arocking or tilting seat lever connected to one side of saidrock shaftand thereby to a degree counterbalancing the weight of the gangs whenthe latter are elevated through the medium of said master lever and rockshaft, thus permitting of the elevation of the gangs by the master leverwith the one hand of the operator and enabling the team to be controlledby the other.

With the above mentioned and other ends in view, .the invention consistsin the novel construction, arrangement, and combination of parts,hereinafter described, illustrated in one of its embodiments in theaccompanying drawings, and particularly pointed out in the appendedclaims. I Referring to the drawings, forming a part of thisspecification, Figure 1, is a perspective view of a cultivatorembodyingmy improvements. Fig. 2, an enlarged longitudinal vertical sectionalview of the upper rear portion of thecultivator frame and thetransversely extending rock shaft carried thereby, the master and theindependent gang lever or beam connected to and adapted to move withsaid rock shaft, being shown in side elevation. Fig. 8, a perspectiveview of the cultivator looking from the drawings.

rear-thereof. Fig. 4:, an enlarged detail top plan view of the rockshaft and actuating lever mechanism shown in side elevation in Similarnumerals of reference designate like parts throughout all the figuresofthe While I have shown my improvements applied to or embodied a"riding cultivator of a specific form or type, it will be obvious fromthe disclosure and explanation herein made that such improvements arenot in any waylimited or restricted to Cultivators of a specific form ortype but are applicable for use in connection with cultivators of anysuitable and convenient m? V a A particular form or embodiment ofcultivator shown in i the accompanying drawings comprises a suitablecultivator frame consisting of side members 1, secured at their forwardends tolthepole 2, and the rear ends to the transversely extending axlesupporting members 3." 4 h i i The gang'arch 4, is rigidly attached tothe side members 1, of the frame and the depending sides of the arch 4:,are suitably braced -by means of brace members 5. To the rear ends ofthe s ide members is the arch are secured the gang couplings 6,connected to the shovel lor lcultivator gangs 7 The axles 8, areadjustably mounted" beneath' the axle frame members 3, through themedium of the bearing sleeV es'Sflan d' the adjusting collars f8". Theaxle pivot sleeves 9, are mounted upon the vertical portions of theaxles 8, and carry the ground wheel 10, of the cultivator thelatterbeing adapted to be moved on their pivots through the medium of footlevers 11 secured to the pivotsleeves Theaxles 8, may be braced throughthe medium of axle braces 12, pivotally connected to'the lower ends ofthe axle pivot sleeves 9, and extending forwardly and secured tobrackets 13, on the side member 1 of the cultivator frame. Asthespecific details of the cultivator form no part of the present inventionand may be varied to meetlthe varying de mands of actual service, thegeneralconstruction of the cultivator proper need not be furtherdescribed in detail. i

As a means of raising and lowering the cultivator gangs independently ofeach other as well as also providing means whereby said gangs may beraised and lowered upon the. side members 1, of the frame through themedium of suitable bearings 15, one of said bearings, 1n the presentlnstance,

being provided with a stationary ratchet sega ment 15, to cooperate witha master lever 16, mounted on-and fixed to the rock shaft 14,'wherebythe latter may be secured in any desired position when operated by themaster lever 16. The ends of the rock shaft 14, are provided withratchet segments 17, adapted to be carried by and to be rockedsimultaneously with therocking movements of the rock shaft 14, and as ameans for providing for the independent movements of the cultivatorgangs, the gang actuating levers 18, are pivotally and independentlymounted upon the ends of the rock shaft 14, so that when thelatter isstationary the independent levers 18, may be moved to any desiredadjusted position and secured in such position in the usual manner byengagement with the ratchet segments 17, the independent levers 18,leading downwardly and beingsuitably connected to the gangs 7, throughthe medium of gang lift rods or members .19. By reason of theconstruction just described, it will be apparent that the levers, 18,and'connected gangs '7, may be actuated and adjusted independently ofeach other while the master lever l6, and rock shaft 14, are secured ina stationary position, and that when the gang levers 18, are inengagement with the ratchet seg ment 17, said segments and levers andgangs will be simultaneously operated in unison with the rockingmovements of the rock shaft 14, and'master lever 16.

' As a means of assisting or accelerating the upward simultaneousmovements of the gangs through the operation of the master lever 16, asWell as in a degree counterbalancing the weight of the cultivator gangswhen the master lever is released from the segment 15, for the downwardmovement of the master lever by the hand of the opcrator, the seatbeams20, are transformed into a rocking or tilting seat lever byfulcruming the beams 20, over the axle supporting members 3, andextending the forward ends of the beams 20, over and above the rockshaft, the free ends of the beams 20, being pivotally connected toforwardly extending crank arms 21, mounted upon the rock shaft 14, itbeing obvious that by reason of the construction just described theweight of the rider or operator in the seat 22, will cause the crankarms 21, to move upwardly and assist in the actuation of the rock shaft14, when the master lever 16, is released from the segment 15*, and iscaused to be moved downwardly in the act of elevating the gangs 7. Theposition of the seat 22, and beams 20, relating to the axle supportingmembers 3 of the cultivator frame may be regulated to a degree throughthe medium of notched fulcrum blocks 23, slidably mounted on and movableto and fro on the seat beams 20, and adapted to cooperate vaiththe'subjacent members'3, of the c'ulti vator frame.

For convenience the seat beams or members 20, which are utilized as arocking or tilting seat lever connected to one side of the rock shaft,are hereinafter referred to in the claims as a seat lever or a seatbeam, it being understood that such term shall include either a pair orplurality of seat beams forming such lever as shown, or a beamconsisting of a single member.

From the foregoing description, taken in connection with theaccompanying drawings, the operation and advantages of my invention willbe readily understood.
